Drought and exogenous abscisic acid alter hydrogen peroxide accumulation and diferentially regulate the expression of two maize RD22-like genes
(Nature Research, 2017)Increased biosynthesis of abscisic acid (ABA) occurs in plants in response to water defcit, which is mediated by changes in the levels of reactive oxygen species such as H2O2. Water defcit and ABA induce expression of ... -
Drought and salinity stress alters ROS accumulation, water retention, and osmolyte content in sorghum plants
(Elsevier, 2017)biotic stresses such as drought and salinity are major environmental factors that influence crop productivity worldwide. These adverse conditions induce osmotic stresses in plant cells by decreasing water availability, thus ... -
